Subject: [PATCH] Initial Yamaha Receiver Implementation

Text Update

Additional additions and better support for volume, and mute.  Cleanup

Added rxv to requirements_all

Added yamaha.py to .coveragerc

Made uppercase, and removed tabs

Added requirements variable

Added doc string for lint

Removed global variable, and simplified state as per balloobs suggestion

Refactored the component with balloobs suggestions

-Added import in the method
- Only get receiver information on init
- A bit of cleanup

Remove up and down volume

Uneeded as this is handled by set volume instead

Fixed a lint build error

More lint fixes

Removed unused imports

Lint Fixes

Simplified if statement

Minor refactoring since the init calls update.

Fixed lint error

Just variable naming change

Added support for an optional name for the receiver.

Better error handling, a bit of refactoring based on balloobs suggestions

Fixed lint error.

Another lint error fix

Changed raise to return

Disable pylint error handling

Pylint broad exception

Made exception handling in the setup platform instead of the constructor.

Lint error fix

Refactored the way devices are found.  This allows for multiple receivers
